Acronym ... Name 2gippapivady (?) Circumradius sqrt[5-2 sqrt(5)] = 0.726543 General of army rox Colonel of regiment rigfix Confer non-Grünbaumian master: gippapivady

Looks like a completely coincident compound of 2 copies of gippapivady, in fact all elements coincide by 2.

As abstract polytope 2gippapivady is isomorphic to 2sprapivady, thereby replacing decagrams by decagons, resp. by replacing gike by ike and quit gissid by tid.
